Sex ratio variation among gynodioecious populations of sea beet: can it be explained by negative frequency-dependent selection?

Evolution; international journal of organic evolution - 1 Jun 2009

Dufay Mathilde, Cuguen Joël, Arnaud Jean-François, Touzet Pascal

Abstract excerpt

This study is devoted to assess sex ratio variation among 33 populations of the gynodioecious Beta vulgaris ssp. maritima in Brittany (France) and to explore the causes of this variation. We showed that three different CMS (cytoplasmic male sterility) cytotypes occurred in populations, but strongly differed for their frequencies and the frequency of their associated nuclear restorer alleles (which counteract the...
